I will try to explain this as clearly as I can. You can draw in any scale, but what you draw will always be in "real world" units. If you draw a line from point A to point B, and the tracker or info box says that the line is 10' long, then it is 10' long regardless of what scale you were drawing in. Whether you are drawing at 1/4"=1'-0" or 6"=1'-0", the standard text probably should be around 7 pt. (might be 8pt. or more if you want larger text, but 7 pt. is around the normal range.) and it will rescale if you change the drawing scale. 1.42 pt. would be microscopic and virtually unreadable on the printed drawing. If you are using text this size, then there is a fundamental misunderstanding of how ArchiCAD handles scale.
So if you want the final drawing to be at 1/4"=1', then set the scale to that and draw away. When you place text or other annotation, that is how it will look when it is printed at 1/4"=1'. If you take this drawing, and change it to 1/8"=1', then all of the text will rescale and appear twice as large relative to the other drawn elements, but that is what it will look like if you send it to Layout with 1/8" scale. Similarly, if you change the scale to 1/2", then all of the annotation will appear smaller relative to all of the other elements, but 7pt text will still print out at 7 pts. (about 3/32").
The best thing you can do is to have someone work with your office who knows what they are doing. There are many trainers who can work remotely, as well. Making mistakes early on in the process will just make the project more expensive, and harder to correct later. You might also try something like Eric Bobrow's "Quick Start" online course, which you can watch over and over again if you don't get the concepts right away.
